[vox-tech] re: DNS and security

[Cylar Z]

Didn't you already post this on Thursday?

In response, I had already posted on Friday a set of
follow-up questions that I needed answered. Let's
recap:

1. DNS. How will editing resolv.conf solve my DNS
issue? My understanding is that that file is the
configuration file for the named daemon. I'm not
running named. Shouldn't need to. A previous install
(Xandros/Debian) ran fine without it. It shouldn't be
required, since my registrar handles incoming DNS, and
outgoing lookups (websurfing) should be handled by my
ISP's nameservers. What I need to know is how to tell
my server where those nameservers are.

2. FTP. Not running an anoymous server. Just need to
upload files for my webpages. Is there a more secure
method I can use (please specify how, don't just say
"yes, there is")?

3. Daemons. Where can I find a comprehensive guide
(including non-free books) to what service does what?
I don't mean a one-line description, I mean someplace
that will really explain it to me in depth. Or, can
someone at least identify the generic ones ESSENTIAL
to my system? Remember, I use ssh to connect and am
running http server. That's all my box does. What
daemons are necessary besides cron, sshd and httpd? 

Thank you in advance.

Matt
